Success! This was my first hydroponic tomato experience. I rescued these seedlings from the Aerogarden, the pods there germinated more than one plant per pod, so I decided to transplant the thinned out plants from the Aerogarden into the same setup I use for my hydroponic lettuce and other leafy greens, using the Kratky method. It worked! BUT, I did make one very rookie mistake, although I was still rewarded with a nice crop of cherry tomatoes for my efforts. And next time I will grow my hydroponic tomatoes in a BIGGER container!!! I hope you try this too! Thank you for watching.
